1. A tool for forming a trench and a plurality of cooling holes within the trench, comprising:
a body comprising a ridge portion extending along an axis, the ridge portion extending along a first side of the tool and being operable to mate with a workpiece to form a trench on the workpiece, the body also comprising first and second recessed portions extending in the direction of the axis along, respectively, opposed lateral sides of the ridge with respect to the axis; and a plurality of electrodes extending from the ridge portion and being oriented to form a plurality of cooling holes within the trench on the workpiece, the electrodes being spaced apart along the direction of the axis.
